Is Turning Up the Bass on Your Car Stereo a Good Idea?

More Bass

If there’s one thing that can add emotion and excitement to your music, it’s adding a little more bass. Bass frequencies, especially those below 80 Hz, can be felt as much as heard at a higher volume level. The tingling in your amps and vibration in your back make a night at a club, your favorite concert or a high-end car stereo system some of the most enjoyable musical experiences available. The problem is, adding bass isn’t always easy. Let’s look at how many people do it and offer a few suggestions for enhancing the low-frequency performance of your car stereo.

Making Bass Takes Power

More BassIf you are an avid reader of our articles, then you know that it takes significantly more power to drive a subwoofer to an output level of 90 dB than it does for a set of tweeters. You can find out more about the physics behind that phenomenon here.

Unless the stereo system in your car has a dedicated amplifier with a switching power supply, it’s likely with 6.5- or 6×9-inch speakers as the largest size, it takes a lot of power to move the speaker cone enough to produce the bottom few octaves of our music.

More BassImagine “Thunderstruck,” “Bohemian Rhapsody” or “Yeah!” by Usher comes on Pandora and you can barely hear the bass line. Instinctively, you look for a way to turn up the bass with the tone control or EQ built into your car radio. More often than not, you are rewarded with a garbled mess that sounds less like music and more like the performer is munching on a rubber floor mat.

As much as this isn’t any fun, it’s really no surprise. That tiny little amplifier built into your radio is designed for moderate listening levels with fairly neutral overall tonal balance. That means, not a lot of bass relative to the mids and highs.

Problem defined. How do we fix it?

Does Adding Power Make More Bass?

More BassWhat if we visited our local car stereo shop and asked to have a 75-watts-per-channel amplifier installed between the factory radio and the speakers? Now, any signal that comes out of the radio is amplified and we don’t run out of power when the bass line kicks in, right?

In the simplest of terms, sure, adding an amplifier to your factory speakers helps a lot. With that said, you are still limited by the small size of the speakers. Worse, you are asking those relatively tiny woofers to move really far to produce bass, as well as midrange information. Unless someone has come up with a way to defy the laws of physics, more excursion always results in more distortion.

Adding an amp added a little bass, but made the midrange sound worse.

Will Upgrading Speakers Add Bass?

More BassLet’s say you skipped the amplifier idea and decided that upgrading to high-quality speakers was a better bet. Do better or more expensive speakers produce more bass than less expensive offerings? There’s almost no definitive way to answer that question in a single paragraph. Some speakers produce less midrange relative to the amount of bass they produce. There are also speakers that play lower than factory speakers. In both cases, the new speakers are typically less sensitive (require more power) than what’s already in your car or truck. In short, you may get the perception of more bass, but more often than not, you’ve ended up with less midrange.

The good thing about upgrading your speakers is that they can likely handle the power from an amplifier with fewer complaints and stress. So, if you upgrade your speakers and add an amplifier, your system might sound pretty good.

The Best Way to Add Bass is to Add a Subwoofer System

More BassImagine if there were a way to add an amplifier and speaker to your car or truck that was dedicated to reproducing bass. I know, it sounds far-fetched, right? Sorry, just kidding.

Adding a subwoofer and driving it with a dedicated amplifier, even if the selection is modest, will offer an impressive improvement in the reproduction of bass in your music. A powered 8-inch subwoofer that fits under a pickup truck seat or in the corner of your truck is a perfect starting point. Best of all, you can turn the bass settings on the radio back down and let the small speakers in your car do their job of reproducing midrange and high-frequency information. The result is a car stereo system that plays louder and sounds amazing.

Of course, there are an unlimited number of options for generic, vehicle-specific and custom subwoofer systems to add more bass to your car stereo. Your local specialist mobile enhancement retailer can help you choose a solution that will meet your needs. Drop by today and have a listen to what they have to offer.

Product Spotlight: Pioneer DMH-W3050NEX

Pioneer DMH-W3050NEX

Pioneer and car audio go together like coffee and cream or a hot dog with ketchup — classic pairings that make sense. On that note, we are going to take a look at one of their NEX-Series double-DIN multimedia receivers in this spotlight. Let’s check out the DMH-W3050NEX.

Pioneer DMH-W3050NEX Platform

For most of us, describing a multimedia receiver as a double-DIN solution would tell us all we need to know. The DMH-W3050NEX is somewhat unique in that the radio’s chassis is single-DIN, while only the front panel shares the standard 4-inch by 7-inch dimensions. This allows the radio to work with many dash kits that won’t accept a radio with a four-inch-tall chassis. Right out of the gate, you’ve got enhanced compatibility in terms of vehicles this works with.

The radio features a 6.8-inch (measured diagonally) capacitive touch front panel with a WVGA 800 x 480-pixel color display behind it. There are six capacitive-touch buttons on the left side of the screen, providing access to menus, voice recognition and volume control.

Communication and Entertainment Options

Every top-quality multimedia receiver, such as the DMH-W3050NEX, includes Android Auto and Apple CarPlay smartphone connectivity. In this case, both platforms feature wireless connectivity, thanks to integrated Wi-Fi. There’s no better way to communicate with family, friends and co-workers; choose the entertainment you want, or get detailed turn-by-turn navigation instructions to almost any location in North America.

The radio includes an HD Radio receiver for FM radio. HD Radio not only improves audio quality on compatible stations, but provides access to additional programming on the digitally broadcast channels. For example, you might have a high-resolution music stream on 97.3, then a non-stop news broadcast on HD2 and sports on HD3, all transmitted on the single 97.3 carrier frequency. Best of all, HD Radio doesn’t require a subscription – it’s completely free. The FM tuner also includes RDS decoding.

The DMH-W3050NEX has a USB port on the rear of the chassis that will charge your phone with up to 1.5 amps of current. You can also connect a USB memory stick (or other Mass Storage Class device) to play WMA, MP3, WAV, AAC or FLAC audio files. When parked, you can also play AVI, DivX, MKV, H.264, H.265, MPG, and several other video file formats. Impressively, the deck supports full HD 1920×1080 resolution video files – something not all multimedia receivers can do.

The radio features a Bluetooth 5.3 transceiver, allowing you to stream audio from a portable media player and select tracks using the ACRVP profile. Speaking of connecting smart devices, the radio works with Pioneer’s Weblink app on your smartphone. You can stream video from a source like YouTube directly to the radio.

Your installer can upgrade the radio with a SiriusXM satellite radio receiver. With SiriusXM, you can enjoy genre-specific entertainment almost anywhere in North America.

Pioneer DMH-W3050NEX
The shallow L-shaped chassis simplifies the installation process and allows the DMH-W3050NEX to integrate into vehicles where a full double-DIN radio won’t fit.

Sound Quality and Signal Processing

The Pioneer DMH-W3050NEX is high-res audio certified, and it will decode digital audio files with sample rates up to 192 kHz. The deck includes a built-in amplifier rated to produce 14 watts of power in compliance with the ANSI/CTA-2006 standard. The front, rear and subwoofer preamp outputs will deliver up to four volts.

In terms of audio processing, the DMH-W3050NEX comes equipped with a 13-band graphic equalizer, adjustable slope and frequency crossovers and signal delays. In standard mode, the radio provides front, rear and subwoofer outputs. In Network mode, the outputs are configured for low, midrange and high-frequency output signals.

The radio is compatible with the iDatalink Maestro RR and RR2 radio integration module. Depending on your vehicle, this interface allows the radio to communicate with the CAN network in your car, truck or SUV. You can see climate controls, dashboard gauges, tire pressure, battery voltage, and even vehicle diagnostic code information. If your vehicle isn’t compatible with the Maestro RR or RR2, your installer can likely connect to the steering wheel buttons using an interface like the Maestro SW.

Pioneer DMH-W3050NEX
The Pioneer DMH-W3050NEX boasts wireless connectivity for Apple CarPlay and Android Auto.

The Heart of a Premium Sound System

If you’re shopping for a well-equipped, high-performance multimedia receiver to upgrade your vehicle, visit a local authorized Pioneer dealer and ask about the DMH-W3050NEX. You can find an authorized retailer near you by clicking the “Find a Store” link from anywhere on the Pioneer website.

Tools of the Trade – The Oscilloscope

Oscilloscope Tools

Our series of articles on what tools are important to test and configure a car audio system upgrade moves on to the oscilloscope. Tools like digital voltmeters, real-time audio analyzers and, of course, hand tools such as screwdrivers, side cutters, wire strippers and a socket set each have their place and importance. When it comes to analyzing the amplitude of electrical signals that change with time, only an oscilloscope can provide an installation technician with the information he needs.

What Is an Oscilloscope?

Oscilloscope ToolsAn oscilloscope is a device with a screen that displays the amplitude of a signal relative to time. The screen has several calibrated squares, each representing an adjustable time base or voltage level. Controls on the scope let the user change the time base and voltage ranges for the type of signal that is under inspection.

Why Is It Important for the Shop I Choose to Own an Oscilloscope?

Oscilloscope ToolsIf you are having an audio system installed in your car or truck, especially if an equalizer or digital signal processor is in the audio signal chain, having a scope is a sure-fire way of setting the amplifier sensitivity controls so they can achieve maximum output without significant distortion. Proper configuration ensures the highest possible signal-to-noise ratio, so hiss and background noise are kept to a minimum.

An Oscilloscope is an Important Tool

Oscilloscope ToolsA scope is also useful for testing the wiring in the car for audio and data signals to confirm that each electrical connection will function as intended. Some installers try to use a digital multimeter set to the alternating current (AC) voltage setting to perform these tests. While the meter may show some amount of information, there is no way to know the shape of the waveform to determine if the signal is digital or analog.

Finding a Quality Mobile Enhancement Retailer

As you search for a shop to work on your vehicle, we recommend that part of the process include a tour of their installation facilities. The install bay and fabrication area need not be spotless if they are working on vehicles, but they do need to have the right tools and supplies. Ask them what they use to set the sensitivity controls on the amplifiers you intend to buy. Hopefully, they have invested in the right tools and they own and know how to use an oscilloscope.

HID versus LED Headlight Bulb Upgrades – Which Is best?

HID LED

When it comes to safe driving at night, upgrading the headlights in your car or truck with HID or LED bulbs can make a dramatic difference in your ability to see long distances. Dozens of articles and videos on the Internet compare the two technologies. Piecing together information from all of them and wading through the marketing hyperbole can take time. Let’s lay out the features and benefits of LED and HID lights to help you choose the solution that will work best in your vehicle.

The Fundamentals of HID Lighting Systems

HID LEDHigh-intensity discharge (HID) lamps operate by applying 80 to 90 volts across a quartz glass arc tube filled with xenon gas at pressures between 70 and 700 psi, depending on the design and application. The current flowing through the arc tube causes the mercury and metal halides in the bulb to ionize into plasma and produce a bright light.

HID bulbs will not light (ignite) from the standard ~85V supply voltage and require an even higher voltage to begin the ionization process. An initial voltage of 15,000 to 25,000 volts is applied to the arc tube where a small amount of argon gas helps the voltage to travel from one electrode to the other and create heat. The process is similar to the way a coil pack creates a spark across spark plug electrodes to ignite the air and fuel mixture inside your engine. The heat created by the spark begins the mercury ionization process. In most applications, the ignition process takes 10 to 15 seconds. The ignition process can be made faster, but this would decrease the life of the bulb and the control ballast.

How Do LED Bulbs Work?

HID LEDBy comparison, LEDs are simpler from a mechanical perspective but more complicated in terms of chemistry. Using a process called electroluminescence, light-emitting diodes are solid-state devices that emit light when current in the form of electrons passing through the semiconductor recombines with electron holes and releases energy in the form of electrons. If you are having sporadic flashbacks to 9th- or 10th-grade chemistry class, then we’ve done our job.

Unlike HID bulbs, LEDs don’t require anything special to get them started, and contrary to popular belief, both HID and LED lighting systems draw roughly the same amount of power when in operation, at about 3.0 amps per bulb.

Drawbacks of HID Bulb Upgrades

HID LEDWhile HID bulbs are amazingly bright and efficient compared to incandescent bulbs, your installer needs to find a location to mount the starter circuitry and high voltage power supply — a device commonly referred to as a ballast. Finding a solid mounting location is critical to the long-term reliability of these components.

HID bulbs require up to 15 seconds to reach their full light output capability. For this reason, they are not an ideal solution for high-beam applications where you need instant light in a “flash to pass” situation.

HID LEDFinally, it is imperative to the long-term reliability of a HID lighting system that it be provided with adequate voltage and current during the startup process. The creation of the >15,000-volt spark can draw as much as 10 amps of current per bulb. The increasingly smaller factory wiring found in modern vehicles, along with the fact that headlights are usually left on during the engine cranking process, can make delivering the full electrical system voltage at a draw of 10 amps per ballast difficult.

When wiring is undersized, you may find that one bulb doesn’t ignite when you turn on your headlights. For this reason, HID system manufacturers strongly recommend the use of a dedicated, high-quality relay harness with a HID bulb upgrade. Direct connections to the battery for power and ground, relays rated for the high starting current of the system and quality all-copper conductors will help to ensure that your ballasts function efficiently and reliably.

Drawbacks of LED Bulbs

HID LEDThe rage over the last few years has been to use LEDs for bulb upgrades. As we mentioned earlier, LEDs reach their full output almost instantly, making them ideal for high-beam and turn signal applications. The primary problem with LEDs bulbs is managing their heat. If the LED chips on the bulb exceed about 257 degrees Fahrenheit (125 degrees Celsius), they can fail quickly. For this reason, LED bulbs include cooling fins in the form of braided copper strands or aluminum bands to help carry heat away from the LED chips. Some designs use small cooling fans. As long as the bulb is fully enclosed in a dust-proof housing, fan-cooled LED bulbs can work well.

HID LEDLED bulb manufacturers have a wide choice of LED chips to use in their bulb designs. The goal of the bulb design is to place a light source in the exact same position as you’d find in an incandescent bulb. The filament in an incandescent bulb is long and narrow, so the LED array should be similar in order to maintain the proper beam pattern. One problem with LED bulbs is that they don’t produce a 360-degree source of light and may require adjustment and tuning to achieve a satisfactory beam pattern.

Is HID or LED Better?

HID LEDDeciding which bulb upgrade is better for your car is like trying to decide if a red Ferrari is better than an orange McLaren. They are as different as they are similar. We spoke with Chris at HIDCOR Industries, a 20-year veteran of the automotive lighting industry, about lighting upgrade options. He told us that he starts each consultation by asking the client why he or she wants to upgrade their lights. The two most common answers are for looks and for performance. If you want that classy, modern white light, then he suggests LEDs are the way to go. They are easy to install and very reliable. If long-distance vision is the goal, then Chris suggests a 4300K (OEM color) or 6000K (pure white) HID upgrade along with a dedicated wiring harness to deliver every ounce of output possible. The HID upgrade is more involved as the ballasts and harness need to be installed properly, so it might be a little more expensive once the dust settles.

Chris explained his reasoning for HID over LED for long-distance lighting needs, but we’ll save that for another article at another time. In the meantime, if you are interested in improving your ability to see safely at night, drop by your local specialist mobile enhancement retailer and ask about the HID and LED bulbs that are available for your vehicle.

Automotive Dashcam Features Explained

Dashcam Features

A dashcam is a compact camera system designed with automotive-specific features to capture video of everything that happens in front of your car or truck. The video files from a dashcam can protect you from fraud or false accusations in the event of an accident. Let’s take a look at some of the most popular options available to enhance the information captured by these amazing safety systems.

Dual Camera Systems

Dashcam FeaturesMany dashcam solutions are available with a secondary camera that can be positioned to monitor the interior of the vehicle or the traffic behind your car or truck. These systems record from both cameras simultaneously to give you a complete record of everything happening. Uber, Lyft and taxi drivers are particularly fond of these dual camera systems to record the behavior of their customers.

Built-In LCD Screen

Dashcam FeaturesTwo types of dashcams are commonly available: Those with and without an LCD screen. In most products, the addition of a feature like a screen is perceived as an upgrade, but with dashcams, this isn’t always the case.

Dashcam systems without displays are often physically smaller, allowing your installer to mount the camera under your rearview mirror for a nearly invisible installation. These dashcams typically include a series of LEDs to indicate when they are powered up and are recording. The drawback to these designs is that you need a smartphone or computer to view videos stored by the system. You will also need to make system configuration adjustments using a phone or computer, so the installation time is longer.

Cameras with integrated displays are often physically larger than those without a screen. Depending on the design of the camera, color displays measure from 1.5 to 3.5 inches diagonally. In addition to letting you look at videos directly on the system, cameras with displays typically have easy-to-understand setup menus right on the unit. Many higher-end cameras include a touchscreen to make adjusting the system even easier.

Integrated GPS Antenna

Another popular dashcam feature is a built-in GPS antenna. The software in the camera will use the information transmitted by the GPS receiver to store vehicle speed and location along with the video information. Most quality dashcam manufacturers offer PC and Apple playback software that will show your location and speed along with the video recording.

Dashcam Features

Integrated Accelerometer

Another great feature to look for is a camera with an integrated accelerometer. These cameras store information about G-forces in all three axes along with the video. Your installer can typically configure the camera to automatically store video files if the camera detects a sudden jolt that might have been caused by an accident.

Parking Mode

Dashcam FeaturesMany solutions offer what is called parking mode. In most cases, when your installer has wired the camera to a constant power source (one that is active even when the ignition is turned off), the camera will stop saving video to the memory card. If the camera detects changes in the video image (from someone or something entering the field of vision) or motion from the built-in accelerometer, the system will wake up and automatically store a video file. In most cases, the recording starts 5 to 10 seconds before the trigger so you can see what led up to the event.

An important note about parking mode: Please make 100% sure that your camera has a low-voltage shutdown feature to prevent the battery in your car or truck from being killed and leaving you stranded. If your camera doesn’t have this feature, several manufacturers make external battery packs and control modules that will reduce or eliminate the load on your vehicle battery. If you don’t drive your car or truck every day, an external battery pack or at least a power management controller is a very wise investment.

High-Resolution Cameras and HDR Mode

Most quality dash cameras have high-definition image sensors capable of storing 1920-by-1080-pixel video files. Compared with VGA or 720p recording, these high-res files allow you to see license plate information, phone numbers or other identifying marks on moving vehicles. Some of the newest cameras record at 4K (4096 by 2160) resolution for an increase in detail of 4.3 times over HD resolution. Yes, this higher resolution with fill up a memory card much more quickly, but the added detail is quite worthwhile. We suggest buying a camera with as much image resolution as possible for your budget.

High Dynamic Range

Another popular feature is called high dynamic range. This is a video contrast compression technology that helps to make dark areas of the image brighter and bright areas darker to make everything in the video easier to see and understand during playback. Turning on HDR processing can help reveal more detail at night or in bright sunlight situations.

Dashcam Features

Wi-Fi-Enabled Dashcam Feature

Dashcam FeaturesThe last feature we will talk about is Wi-Fi. Many premium cameras include an integrated Wi-Fi hotspot that allows you to connect your phone to see videos or make adjustments to the system. This is a particularly convenient feature on cameras that don’t have a touchscreen as it makes adjusting menu options quick and easy. Apps for iOS and Android-based smartphones are typically available for dashcams with Wi-Fi built in.

Some advanced dashcams include the option to automatically connect to an internet hotspot to upload video files to the cloud to make information access easy and efficient.

Protect Yourself with a Car Dashcam

If you are concerned about fraud from other drivers or pedestrians, or you want undeniable proof of who’s at fault in the event of an accident, then you owe it to yourself to invest in a quality dashcam. Drop by your local specialist mobile enhancement retailer today to find out more about the systems that are available and arrange for expert installation in your vehicle.
